The Battle of Shanghai was a large urban battle between the Empire of Japan and the Republic of China in the Chinese city of Shanghai during the Second Sino-Japanese War. It lasted from August 13, 1937, to November 26, 1937, and was arguably the single largest and longest battle of the entire war, with it even regarded by some historians as the first battle of World War II. It resulted in the Japanese capturing the city and heavy destruction to the city.

Iwane Matsui was a general in the Imperial Japanese Army and the commander of the expeditionary force sent to China in 1937. He was convicted of war crimes and executed by the Allies for his involvement in the Nanjing Massacre.
